I'm not a lawyer either,but I slept at a Holiday Inn Express last night!
I think if it was a portfolio page, "legally" it would not fall under fair use, as there are certain criteria you must meet..you would have an issue with the first point shown below. As of today Getty has not sued anyone over 1 image, and I highly doubt they would pursue something of this nature, fair use or not a judge would probably be inclined to award the least amount, which wouldn't even cover the cost of filing the papers.
Section 107 contains a list of the various purposes for which the reproduction of a particular work may be considered fair, such as criticism, comment, news reporting, teaching, scholarship, and research. Section 107 also sets out four factors to be considered in determining whether or not a particular use is fair.
Section 107 of the United States Copyright Act lists four factors to help judges determine, and therefore to help you predict, when content usage may be considered "fair use."
1. The purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes.
If a particular usage is intended to help you or your organization to derive financial or other business-related benefits from the copyright material, then that is probably not fair use.2. The nature of the copyrighted work.
Use of a purely factual work is more likely to be considered fair use than use of someone's creative work.3. The amount and substantiality of the portion used in relation to the copyright protected work as a whole.
There are no set page counts or percentages that define the boundaries of fair use. Courts exercise
common-sense judgment about whether what is being used is too much of, or so important to, the original overall work as to be beyond the scope of fair use.4. The effect of the use on the potential market for or value of the copyright protected work.
This factor looks at whether the nature of the use competes with or diminishes the potential market for the form of use that the copyright holder is already employing, or can reasonably be expected soon to employ, in order to make money for itself through licensing.http://www.copyright.gov/fls/fl102.htmlyou might want to read this is well:
